The invention relates to a device for encapsulating solid flavoring substances, particularly tea or coffee, dissolved in a liquid, particular water, with a wing-shaped rotary slider supported rotational about a rotary axis between an initial position and an end position, which in its end position limits a space accepting the solid flavoring substances, with the device being embodied for the installation in a container, with its top showing with an opening for filling in or releasing the liquid, which can be closed by a lid, which is subject to a rotary motion for opening and closing the container opening, as well as further a container, particularly a drinking cup, with a preferably cup-shaped container housing, which is limited by a wall and a bottom, and which comprises a container opening at the top opposite the bottom for filling in and releasing a liquid comprising solid flavoring substances, particularly tea or coffee, and with a lid for closing the container openings, with the lid being embodied such that for closing and opening the container opening it is subjected to a rotary motion, showing such a device.
Such a device, for example known from EP 1 029 474 A1, allows a targeted termination of the brewing process of the solid flavoring substances by the user interfering, with here the user rotating the rotary slider from its original position into its end position. For this purpose, first the solid flavoring substances, for example tea, are added to the liquid so that it comes into contact with the preferably preheated liquid and accordingly releases flavoring substances thereto. Here the rotary slider is in its initial position. After the brewing period has expired the rotary slider is subjected to a rotary motion, by which it is moved from an initial position into an end position and here entrains the flavoring substances into a space limited by the rotary slider in its end position. When the entirety of the solid flavoring substances has been brought into said space by a rotation of the rotary slider it has no longer any contact with the surrounding liquid so that here the brewing process of the solid flavoring substances in the liquid is ended in a targeted fashion. Due to the fact that the rotary slider in its end position limits the space now comprising the flavoring substances, these flavoring substances are now encapsulated and separated from the remaining liquid. This way it is prevented that the flavoring substances can leave said space in an undesired fashion and once more come into contact with the surrounding liquid. This way, even after the end of the brewing process it is not necessary to immediately remove the solid flavoring substances from the liquid.
Even if the above-mentioned device has proven in practice, there is a need for a further simplification of its operation.
This objective is attained according to a first aspect in a device for encapsulating solid flavoring substances, particularly tea or coffee, added to a liquid, particularly water, with a wing-shaped rotary slider supported rotational about a rotary axis between an initial position and an end position, which in its end position limits a space accepting the solid flavoring substances, with the device being embodied for the installation in a container, with its top comprising an opening to fill in or discharge the liquid, which can be closed by a lid, with the lid being subjected to a rotary motion for closing and opening the container opening.
Further this objective is attained in a second aspect of the invention in a container, particularly a drinking cup, with a preferably cup-shaped container housing, which is limited by a wall and a bottom and with its top opposite the bottom comprises a container opening to fill in or discharge liquid comprising solid flavoring substances, particularly tea or coffee, and with a lid for closing the container opening, with the lid being embodied such that for closing and opening the container opening it is subjected to a rotary motion, characterized in a device according to the first aspect of the invention. According to the invention the rotary motion of the lid of a container is used in its closed position also to pivot the rotary slider into its end position in order to encapsulate the solid flavoring substances in the space limited by the rotary slider in its end position. The rotary motion of the lid is therefore transferred to the rotary slider. This is achieved according to the invention such that via an engagement means the rotary slider can be brought to engage the lid at least during its rotary motion for closing the container opening and thus can be rotated into its end position. The advantage of the invention therefore comprises that for bringing the rotary slider into its end position, on the one hand, and for the closing motion of the lid, on the other hand, no separate handling is required but jointly a single rotary motion is sufficient, by a respective torque being applied upon the lid. Using a single handling measure here according to the invention both the lid can be brought into its closed position as well as the rotary slider can be brought into its end position for encapsulating the solid flavoring substances.
Preferred embodiments and further developments of the invention are disclosed in the dependent claims.
In the following, a preferred exemplary embodiment of the invention is explained in greater detail based on the attached drawings. It shows:
The drinking cup 2 comprises a cup-shaped housing and/or a cup-shaped hollow body 4, which is limited by a lateral wall and is closed at its base by a bottom. A ring 6 is arranged at the top of the cup-shaped hollow body 4 opposite the bottom, which limits an opening 8. The opening 8 serves for filling in liquids into a drinking cup 2 and for discharging liquids from the drinking cup 2 and thus it is also called the container opening 8. The hollow body 4 and the ring 6 placed thereupon are embodied rotary symmetrical and thus form a rotary body with its rotary and/or central axis being shown in dot-dash lines in
Accordingly, both the hollow body 4 and the ring 6 show an annular cross-section.
The drinking cup opening 8 embodied at the top of the drinking cup 2 and limited by the ring 6 can be closed with a lid 10.

Further,
The rotary slider 14, which alternatively can also be called a rotary sword or a rotary wing, comprises in the exemplary embodiment shown the form of a plate, similar to the fixed wail element 12, and also approximately the same relative dimensions and extends, similar to the wall element 12, radially from its rotary axis 15 and/or when installed in the drinking cup 2, from its rotary and/or central axis 5 radially towards the inside of the wall of the insert 4b. In order for the rotary slider 14 not losing its mobility, here contrary to the fixed wall element 12, no connection is provided between the external edge of the rotary slider 14 and the interior side 4c of the insert 4b, with the gap between the rotary slider 14 and the insert 4b being kept as small as possible.
For a rotational support of the rotary slider 14 about the rotary axis 15 hinge elements are provided at the wall element 12, which in the exemplary embodiment shown comprise sheath-shaped elements 16a, 16b according to

In the following the operation of the above-described arrangement is explained in greater detail. First, the drinking cup opening 8 must be open by the lid 10 being removed. Then through the opening of the drinking cup 8 a substance to be processed is filled into the hollow space of the insert 4b of the hollow body 4, which usually represents tea or ground coffee and thus represents a solid aromatic. In order to ensure that this substance is filled at the desired “correct” side of the wall element 12 and the rotary slider 14 and thus in the desired “correct” section of the hollow space of the insert 4b the rotary slider 14 should be pivoted back into an initial position to such an extent that it essentially abuts flat at the fixed wall element 12, namely at the side of the wall element 12 which points away from the closure element 18 and thus is not projecting beyond the connection element 18. This is the side of the wall element 12 facing the observer of
Subsequently, preferably after a predetermined brewing period has expired, the rotary slider 14 is subjected to a rotary motion about its rotary axis 15 in the direction of the arrow A shown in
In order to set the rotary slider 14 into the above-mentioned rotary motion in the direction of the arrow A for encapsulating the substance the lid 10 is used in the manner described above. When here the lid 10 is rotated about its rotary axis 11 (
In the above-described exemplary embodiment the space encapsulating the solid flavoring substances, which is limited by the fixed wall element 12 and the rotary slider 14 being in its end position, shows an essentially constant cross-section over its axial length. Alternatively it is also possible to embody the rotary slider and/or the fixed wall element such that the above-mentioned space tapers in the end position of the rotary slider in the direction towards the bottom 4d and, if applicable, the rotary slider in its end position and the fixed wall element 12 essentially contact in a section distanced from the opening of the drinking cup 8 to the floor 4d.
While in the above-descried exemplary embodiment a bayonet closure construction is used to optionally rotate the lid 10 into its closed position or into its open position, of course it is also possible alternatively to provide a threaded closure connection.
Finally it shall be mentioned that the above-described device, instead of the exemplary embodiment described, may be made entirely from plastic.
